Summary:                    bootstrap of CMake can fail when a wrong libmd is
found
Description: 
Utilities/cmlibarchive/CMakeLists.txt uses

IF(CRYPTO_LIBRARY)
  LIST(APPEND ADDITIONAL_LIBS ${CRYPTO_LIBRARY})
ELSE(CRYPTO_LIBRARY)
  IF(NOT OPENSSL_FOUND)
    FIND_LIBRARY(MD_LIBRARY NAMES md)
    IF(MD_LIBRARY)
      LIST(APPEND ADDITIONAL_LIBS ${MD_LIBRARY})
    ENDIF(MD_LIBRARY)
  ENDIF(NOT OPENSSL_FOUND)
ENDIF(CRYPTO_LIBRARY)

This fails if libmd exists in the search path but is actually from the GROMACS
simulation package, rather than the crypto message digest library. A
try_compile() test after a successful find_library() would allow the CMake
bootstrap to be more robust.

Steps to Reproduce: 
1. Use ./bootstrap on a system with GROMACS (http://www.gromacs.org) installed
and http://martin.hinner.info/libmd/ not installed.

2. Do make

3. Observe that CMake tools cannot link because of the unsatisfied dependencies
of the inappropriate -lmd.

Additional Information: 
I was able to successfully build CMake on this system by removing the resulting
"-lmd" from all the links.txt files, using a combination of sed -i and find.
